COMPOSITION OF MATTER FOR SAVING COAL DURING COMBUSTION.

SPECIFICATION forming partof Letters Patent No, 541,025, dated June 11, 1895. Application filed 0ct0l1er 30, 1894. Serial No- 7, specimens) T0 at whom it may concern:

' Be it known that I, DAVID GRAY STOKEY, of

Dallas, in the county of Dallas and State of.

In the use of coal as a fuel, a considerable wastage results from the imperfect combustion of the vaporized carbon, that is thrown off from the fuel as it is burned, and passes away through draft conduits to the open air. The object'of my invention is to provide a cheap and practical composition of ingredients, that when applied to the fuel in a stove will intensify-combustion, prevent clinkers forming in the fire chamber of the stove, aid to burn the smoke, and thus prevent the formation of soot, and by uniting with the volatilized products of combustion of the coal, insure their more perfect combustion, and effeet a marked saving of the 'coalused as fuel.

My improved composition of matter for saving fuel, consists of the following ingredients combined in about the proportions stated.

Formula: Salt, two pounds; charcoal, (pulverized,) two and one-half ounces; saltpeter, one ounce; carbonate of zinc, one-half ounce; borax, (pulverized,) one-fourth ounce.

The above named ingredients are mixed and dissolved in sufficient cold water to properly efiect their blending together; and to apply the composition, a portion of the liquid matter is sprinkled on the coal before it is burned.

It is claimed for the above specified composition of matter, that it will when vaporized by heat, assimilate with the carbon gas thrown off from the burning coal, and render it more inflammable, so that a more perfect combus tion results, and the formation of soot is avoided.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

The herein-described composition of matter to be used with coal to perfect combustion and save fuel, consisting of water, salt, charcoal, saltpeter, carbonate of zinc, and borax, mixed and combined in about the proportions specified.

DAVID GRAY STOKEY.
